[0029] In order to further understand the content, characteristics and effects of the present application, the following examples are listed and described in detail as follows with reference to the accompanying drawings:

[0030] The spray hole of the existing nozzle is easy to be blocked, causing uneven water spraying of the nozzle and difficulty in cleaning.

[0031] Please see Figures 2-5 The water spraying head provided by the embodiment comprises a water spraying member 1, a water inlet member 2, a shaft core 3 and an elastic member 4. One end of the water spraying member 1 is provided with a cavity 10, and the other end of the water spraying member 1 is provided with a water spraying opening 11 which is communicated with the cavity 10. The water inlet member 2 is arranged on the water spraying member 1, and is used for covering the cavity 10. The water inlet member 2 is provided with a water inlet opening 21 which is communicated with the cavity 10. The shaft core 3 is movably arranged in the water spraying opening 11, and one end of the shaft core 3 extends into the cavity 10. The outer circumferential surface of the end of the shaft core 3 which is away from the cavity 10 is provided with a plurality of guide grooves 31, and the extension direction of the guide grooves 31 is consistent with the length direction of the shaft core 3. When the shaft core 3 is located in the water spraying opening 11, the guide grooves 31 and the inner side wall of the water spraying opening 11 form a water spraying channel 12. The elastic member 4 is arranged in the cavity 10, and the two ends of the elastic member 4 are in contact with the bottom of the cavity 10 and the shaft core 3 respectively. The elastic member 4 is used for applying an elastic force to the shaft core 3 to insert the shaft core 3 into the cavity 10.

[0032] Specifically, the water inlet 2 is covered on the water outlet 1 to form a closed space in the cavity 10, so that the water flows into the cavity 10 through the water inlet 21 and is sprayed out through the water outlet 11, thereby realizing the water spraying function of the water outlet. Preferably, the number of guide grooves 31 is twelve, and the water in the cavity 10 is uniformly sprayed out through different water spraying channels 12 formed between the guide grooves 31 and the inner side wall of the water outlet 11, thereby improving the uniformity of the water spraying of the water outlet. When the water outlet needs to be maintained, an external force is applied to the shaft core 3 to drive the shaft core 3 to move outward in the water outlet 11 and compress the elastic member 4, so that the guide grooves 31 and the water outlet 11 are separated from each other, thereby making the guide grooves 31 open during the outward movement of the shaft core 3, so as to facilitate the removal of impurities blocked in the guide grooves 31 or the water outlet 11, thereby realizing the convenient cleaning and anti-blocking function of the water outlet. In addition, the two ends of the elastic member 4 are in contact with the bottom of the cavity 10 and the shaft core 3, respectively. After the water outlet is cleaned, the elastic member acts on the shaft core 3 and drives the shaft core 3 to move back to its original position, and finally the water spraying channel 12 is formed between the guide grooves 31 and the water outlet 11.

[0033] It can be understood that one end of the shaft core 3 penetrates the cavity 10 and extends towards the water inlet 2 at the port of the cavity 10. When the water outlet needs to be cleaned, the water inlet 2 is removed from the water outlet 1, and the end of the shaft core 3 away from the water outlet 11 is acted on to make the shaft core 3 move from the cavity 10 towards the outside of the water outlet 11. In this way, the guide grooves 31 and the water outlet 11 can be separated from each other, thereby facilitating the cleaning of impurities in the guide grooves 31 and the water outlet 11, and improving the convenience of the water outlet.

[0034] In other embodiments, the shaft core 3 with different numbers of guide grooves 31 and / or different cross-sectional areas of guide grooves 31 is replaced, thereby facilitating the change of the water spraying fineness and uniformity of the water outlet, and improving the adaptability of the water outlet to different water spraying requirements.

[0035] In the embodiment, the shaft core 3 is formed with a boss 32 at the end away from the cavity 10, and the guide groove 31 extends on the outer circumferential surface of the boss 32; the port of the water outlet 11 is formed with a recess for accommodating the boss 32, and the inner side wall of the recess can act on the outer side wall of the boss 32; the boss 32 is formed at the end of the shaft core 3 away from the cavity 10, so that the port of the water outlet 11 acts on the boss 32 to position the boss 32, thereby realizing the positioning of the shaft core 3 by the water outlet 1 and the elastic member 4 at both ends of the shaft core 3, and effectively preventing the shaft core 3 from falling off the elastic member 4. It can be understood that the guide groove 31 extends on the outer circumferential surface of the boss 32 to facilitate the water outlet channel 12 passing through the boss 32 and the water outlet 11, so that the water in the cavity 10 can be smoothly sprayed out of the water outlet 11.

[0036] In other embodiments, the cross-sectional area of the boss 32 perpendicular to the axis direction increases successively from the direction away from the shaft core 3, that is, the cross-sectional shape of the boss 32 parallel to the axis direction is trumpet-shaped or angular from inside to outside. Preferably, the boss 32 and the port of the water outlet 11 are respectively trumpet-shaped; by correspondingly arranging the trumpet-shaped boss 32 and the water outlet 11, different water outlet channels 12 are arranged at an angle to each other and away from each other at the outlet end of the water outlet 11, thereby expanding the water outlet angle of the water outlet 11, and thereby improving the water outlet angle and water outlet area of the water outlet head; in addition, by the trumpet-shaped boss 32 and the water outlet 11, the outer side of the boss 32 and the inner side of the water outlet 11 are arranged at an angle to the axis thereof, when the shaft core 3 moves from the cavity 10 towards the water outlet 11 (that is, moves outward along the axis direction of the water outlet 11), the boss 32 moves under the driving of the shaft core 3 and the gap between the boss 32 and the water outlet 11 gradually increases, thereby facilitating the impurities to separate from the guide groove 31 and the water outlet 11, and helping to improve the cleaning effect and convenience of the water outlet head; it can be understood that by changing the angle of the trumpet-shaped boss 32 and the water outlet 11, the water outlet angle and water outlet area of the water outlet head can be adjusted. It can be understood that the guide groove 31 is arranged in an arc shape along the outer circumferential surface of the trumpet-shaped boss 32, effectively reducing the bending degree of the guide groove 31, making the water outlet channel 12 more smooth, avoiding the need for the guide groove 31 to be arranged in a zigzag shape corresponding to the outer circumferential surface of the boss 32 when the boss 32 is stepped, and helping to reduce the resistance of the water flow when passing through the water outlet channel 12, thereby ensuring the water outlet pressure of the water outlet head.

[0037] In the embodiment, the shaft core 3 is disposed on one end of the cavity 10 with a detachable baffle 5, and the end surface of the baffle 5 can act on one end of the elastic member 4; the baffle 5 is provided with an opening, and the middle part of the shaft core 3 can be embedded in the opening of the baffle 5. When the baffle 5 is installed on the shaft core 3, the end of the elastic member 4 is in contact with the baffle 5, and the elastic member 4 acts on the shaft core 3 through the baffle 5, so that the elastic member 4 can limit and apply a restoring force to the shaft core 3; when the water spraying device 1 needs to replace different numbers of guide grooves 31 and / or different cross-sectional area guide grooves 31, the baffle 5 is removed from the shaft core 3, so that the shaft core 3 is separated from the elastic member 4, and the shaft core 3 is taken out of the water spraying port 11.

[0038] In the embodiment, the elastic member 4 is a spring, one end of the shaft core 3 in the cavity 10 can penetrate the spring, and the diameter of the spring gradually increases or decreases along the length direction; the end of the spring with large diameter is in contact with the bottom of the cavity 10, and the end of the spring with small diameter is in contact with the end surface of the baffle 5. Preferably, the elastic member 4 is a horn-shaped spring, when the shaft core 3 is disposed in the spring, the end of the spring with small diameter is in contact with the baffle 5 of the shaft core 3, so that the cross-sectional area of the baffle 5 can decrease with the diameter of the spring, thereby reducing the resistance generated by the baffle 5 to the water flow in the cavity 10, so as to help to improve the water pressure in the cavity 10, and further to ensure the water pressure of the water spraying head.

[0039] In the embodiment, the axes of the water inlet 21, the water spraying port 11 and the shaft core 3 are on the same straight line, and the end of the shaft core 3 towards the water inlet 21 is conical or hemispherical. By arranging the water inlet 21, the water spraying port 11 and the shaft core 3 on the same straight line, the water spraying device 1 and the water inlet device 2 are arranged in a straight line, which can reduce the volume of the water spraying head and make the structure of the water spraying head more compact; the end of the shaft core 3 towards the water inlet 21 is conical, and the tip (or the end with small cross-sectional area) of the cone is directed towards the water inlet, which greatly reduces the blocking area of the end of the shaft core 3 to the water inlet 21, effectively reduces the resistance of the end of the shaft core 3 to the water flow at the water inlet 21, and helps to ensure the pressure in the water spraying head.

[0040] In addition, when one end of the shaft core 3 extends in the cavity 10 towards the water inlet 2, the relative position between the water inlet 2 and the water outlet 1 is adjusted to make the water inlet 21 close to the cavity 10, so that the end of the shaft core 3 is closed to the water inlet 21 under the elastic force of the elastic member 4, thereby achieving the effect of cutting off the water flow and effectively preventing the remaining water in the external pipeline from continuing to flow out; when the external pipeline provides water pressure to the water outlet, the water pressure in the water inlet 21 is increased and reaches the opening pressure of the shaft core 3, the water pressure drives the shaft core 3 to move against the elastic force of the elastic member 4, so that the water flows from the water inlet 21 into the cavity 10 and is stably sprayed out through the water outlet 11, thereby achieving the effects of automatically opening the water inlet 21 and stabilizing the water pressure of the water outlet.

[0041] In other embodiments, a plurality of mounting grooves 33 are formed in the shaft core 3 for embedding the baffle 5, and the mounting grooves 33 are distributed along the length direction of the shaft core 3; by adjusting the position of the baffle 5 in different mounting grooves 33, the distance between the baffle 5 and the bottom of the cavity 10 is changed to change the length of the elastic member 4, thereby changing the elastic force of the spring on the shaft core 3 and changing the pressure of the water flow entering the water outlet, thereby satisfying the function of freely adjusting the pressure of the water outlet. Preferably, the mounting grooves 33 are arranged in a ring shape to enable the baffle 5 to be installed on the shaft core 3 at multiple angles, thereby greatly improving the installation efficiency of the baffle 5 and helping to improve the convenience of the water outlet.

[0042] In one of the embodiments, one end of the water inlet 2 is detachably connected to one end of the water outlet 1 by threads; preferably, a groove 22 is formed on the side of the water inlet 2 facing the water outlet 1, and corresponding threads are formed on the outer side wall of the end of the water outlet 1 facing the water inlet 2 and the inner side wall of the groove 22, so that one end of the water outlet 1 is screwed into the groove 22, thereby achieving the detachable connection of the water inlet 2 and the water outlet 1 in a simple way.

[0043] In other embodiments, when it is necessary to adjust the elastic force of the spring to adjust the water flow pressure entering the water outlet through the end of the shaft core 3; by screwing the threaded end of the water outlet 1 into or out of the water inlet 2, the distance between the bottom of the groove 22 and the shaft core 3 is adjusted, so that the bottom of the groove 22 acts on the shaft core 3 to make the shaft core 3 move the baffle 5 against the elastic force of the spring and compress the spring, thereby adjusting the length of the spring and achieving the purpose of adjusting the elastic force of the spring, and also achieving the function of adjusting the water flow pressure entering the water outlet.

[0044] In the embodiment, the anti-loosening structure 6 is arranged between the water inlet part 2 and the water spraying part 1, and is specifically an anti-loosening washer or an anti-loosening nut. During installation, the anti-loosening structure 6 is sleeved on the threaded end of the water spraying part 1, and then the threaded end of the water spraying part 1 is screwed into the groove 22 of the water inlet part 2. When the water spraying part 1 and the water inlet part 2 are connected, the anti-loosening structure 6 acts on the water inlet part 2 to prevent loosening of the water inlet part 2, thereby preventing loosening between the water inlet part 2 and the water spraying part 1 and improving the structural stability of the water spraying head. The anti-loosening washer and the anti-loosening nut are both prior art, and will not be described here.

[0045] In the embodiment, the first sealing part 7 is arranged between the water inlet part 2 and the water spraying part 1, and is located at the bottom of the groove 22. When the water inlet part 2 and the water spraying part 1 are threadedly connected, the end of the water inlet part 2 and the bottom of the groove 22 jointly act on the first sealing part 7 to form a seal between the water inlet part 2 and the water spraying part 1, thereby sealing the water spraying head to maintain the pressure in the cavity 10 and prevent water leakage.

[0046] In the embodiment, the water inlet connector 23 is formed at the end of the water inlet part 2 away from the water spraying part 1, and is in communication with the water inlet 21. The water inlet connector 23 is connected to an external pipeline by screwing to achieve the purpose of supplying water to the water spraying head from an external water source. In addition, the second sealing part 8 is arranged at the bottom of the water inlet connector 23, and is used to seal the water inlet connector 23 and the external pipeline. Specifically, the first sealing part 7 and the second sealing part 8 are both sealing rings, which are prior art and will not be described here.

[0047] All the technical features in the embodiment can be freely combined according to actual needs.

[0048] The above description is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiment are within the scope of the technical solution of the present application.
